International commercial law is constantly evolving to adapt to globalization. In this context, two instruments stand out for their influence in the harmonization of international private law: the UNIDROIT Principles and the Principles of European Contract Law (PECL).

The UNIDROIT Principles, developed by the International Institute for the Unification of Private Law, are a set of non-binding (soft law) that promote values ​​such as:

  • Good faith in transactions.

  • Freedom of contract.

  • The pacta sunt servanda principle (contracts must be fulfilled).

The PECL, developed by the Lando Commission since 1976, seek to identify a common core among European legal systems. Although they are not mandatory, they serve as a reference for judges, arbitrators, and legislators interested in unifying criteria.

Both bodies of law share a common objective: to offer modern, flexible, and universal rules that facilitate international transactions and strengthen trust between parties.

At Dragón de Fuego, these principles guide our practice in maritime, commercial, and foreign investment contracts, helping our clients operate under the highest international standards.
